To all whom it my concerns; 7

Be it known that I, LomsA. FRI D AN,

a citizen of the United States, and a resident of the city, county, and State of New York, have invented a certain new and-useful Improvement in Machines for; Filling Receptacles, of which the followingis a specification. a

The object of this inventionisto. provide a means for filling receptacles, such astuhes, vials, or otherv containers, particularly those having a small mouth or'aperture'through which a powdered fillingtmaterial isgadapted to enter. The material-with which; the containers are adapted to be; filledsis preferably a powdered substance. It isgwell known that various chemical owders, such as chloride of lime and the like, arejdiflioul-t to handle in damp weather, and therefore very 'fiicult to place within wntainersrapidly, The main object therefore of thisvinvention is to provide a machine which willat alltimes operate, effectively to rapidly and expeditiously fill containers of the character. above referred to with any powdered substance.

With these objects, and other objects which may hereinafter appear, inqview', I have devised the articular arrangement of parts set forth be ow and more particularly pointed out in the claims appended hereto.

Reference is to be had to the apcompanying drawing, forming a parthereof in Figure 1 is a plan view of anembodim'ent of one of. the filling elements, togetheruwith its vibrating mechanism, i,

Refern'ng'to the embodiment of m inventlonwshowm in-Figures l and 2. ere-is shown a motorihpwhieh is suitably supportedlmfanyv-desinedmanner and is provided with its-shaft Q rotated .in the usual mm known manner. "This shaft 2'is eccentric on-its outer end asat? 3, and mounted. thereon-is-the casing '4"in which is held under sprung tension, a'ball- 5 on the end of the arm 6. It will thus be seen that rotationof thelshaft 2ewi-ll cause oscillation of the dis ing w-Thee'ball 5- wct'szas a universal joint forathe arm'fito whichit is attached so that the 6, .isg1by;the-[rotation ot the shaft 2, m idl wibratedy This particular vibratin devicebefore mentionedtis=well known an In; forms no partjof myiinvention. Thelarm 6 is pivotally-mountedlas at 7 in the bracket 8 which "extends from the .casin of themotor 11, and seoutied 'toithe outeror ree end of: the 76 amais aibracket' 9thavinga pair of parallel z "arms 108361111. 'a i ,iAcups-ili2lis held inean openin in the 11pperafmrihfl 'byivmea s) of the c lar l3 and .thiacup $12: (is provi d with the conical fill- 80 ingopeni'ngl and extending from the lower end of this conical opening 14 is the downwardly widening conical opening 15- into which theopen upperle'nd of the receptacle to e fi ledzisninse zted --i l J, 11 is provided lwith ia vecephae support l6 which extends through;the arm and is held; thereon by the collar 1' (!-wh ieh ,is held inplace by theiscrew 18.; The receptacle-support is provided with an upward-1y; widening conical o ning 19 from-the lower end of which exten a downwardly widening; conical discharge openln 29,.w 31;

romsthe foregoing the operation of this 96 embodimentiof-my invention-will be readily understood. The arms 10 and 11 of the supporting bracket 9 a-re preferably resilient so that they maybe spread apart or distended as indicatedin dotted lines in Figure 2, 100 so that the receptacle to be filled can pass between the cup 12 and support 16 and can be held therein as indicated at 21 in Figure 2, with its lower end resting in the conical openingl9 and-its upper end or mouth inserted in, the, opening 15 in the cup. The

advantage of the cooperating conical openings 15 and 19 is readily apparent as they center and hold concentric receptacles irrespectiye ,of their varying diameters. After the tube'or other receptacle 21 is in place as shown in Fi re 2, a desired quantity of the filling powc er is deposited in the wnicel openlng 14 in the cup 12 and the motor is set in operation. By means pf the mechanian heretofore described the shaft 6 with the attached bracket 9 is thus rapidly vibrated, causing the powder held in the 0 ning 14 in the cup to be rapidly shaken own into the tube or receptacle 21. The rapid vibrw tions of the bracket 9 prevent the w-der from building up, clinging or adhering to the interior wall of the opening 14, and thus all that is deposited therein is quickly and efiectively shaken down into the receptacle 21: The discharge opening 28 in the support 16 is used menely to allow any stray surplus powder which may not fall into the receptacle to fell thnough and thus keep the support 16 clean.

In the embodiment :of my invention as shown in Figure 3, I have shown a fixed base 22 on which is mounted a motor 23 or other driving means. This motor drives a ratchet wheel 25 by means of llhe belt 24, the'ra tohet Wheel being suitably mounted in a standard 26 affixed to the base '22. An am 27 is pivoted at 28 in a standard 29 extending upwardly [from the base 22 and one end of the aim engages the ratchet wheel 25 and is held in engagement therewith by means of the sprin 30. In the other end 'of the arm 27 is mxn nted a cup 3 1, this on corresponding in all respects to the cup 125 own in Figures 1 and 2, and its the like openings 14 and 15 for the purposes heretofore described.

Below the cup 31 is the receptacle support $2 which has a conical o ning 33 to receive the lower end of the ptadle 21. "This receptacle support -'is mounted loosely in the base so that it can move vertically therein and is forced upwardly by the spring 34. It *Wi ll thus be seen that the reoeptacle21 resting inthe conical opening '33 'is he ld with its upper end firmly iorced'into the opening 1 5 in the cup by the tension of the spring 34. The rotation of the ratchetwheel 25 causes vibration of the arm 27 so that the powder time the ailin opening 14 is rapidly shaken down into receptacle 21 "by these vibrations The spring 84 holds the re ceptaele 2Q tightly in the opening 15 at all times. After the receptacle 21 is filled, it is removed, and an empty one is inserted be tween the tiller and support and the pro cedure is repeated.

In Figures 4, 5 and 6 of the drawings, I have shown amachine for filling a. number of receptacles. machine is providedwith a tramlefifi in-which 'is-join'neled at 36 and'37 a attached filling shaft 38 suitably driven by a chain 39 from a motor 40 or other source of power. EX- tending upwardly from the frame 35 is a standard 41 and mounted to rotate horizontally on the upper end thereof is an internal gear 42 on top of which is secured a. table 43. The internal gear 42 is driven by a pinion 44 on a vertical shaft 45 which is .Sflpported in a. bracket 47 on the frame.

Fixed on the shaft 45 is a pulley 46 which is rotated by a belt 49 extending from a pulley 50 on the shaft 38 and over the pulleys 48 supported in the bracket 47.

Mounted on the shaft 38 is a ratchet wheel 51 and this engages the lower end of a rod 52 which passes vertically through the standard 41 and is movable therein. On the upper end of the rod 52 isfixed a table 53 and fixed in said table adjacentthe outer edge thereof are a plurality ofcnps 54, these cups being identical in construction with those shown as 12 in Figures 1 and 2, and as 31 in Fi ure 3, of the drawings. Fixed in the tabe 43, which is below the table 53, are the receptacle supports 32 which are identical in construction with that lower end of the rod 52 on the ratchet wheel 51.

From the foregoing the operation of this embodiment of my invention will be readily understood. The cups 54 can be filled one after another with the filling compound as they pass any desired part of the machine. The filling of these cups with the powdered substance can be done either by hand or by machine, as desired. As the tables 43 and 53 are rotated, the upper table 53 with its cups is constantly vibrated by means of t e ratchet wheel 51. and thus all the filling compound that is placed with in the cups 54 is shaken down into the re ceptac'les 21 that are placed and held below them as heretofore described.

'From the foregoing it is obvious that my invention is not to be restricted to the em hodiments herein shown but is broad enough to cover all structures coming within the having a pluralit of filling openings, the resilient supports or the receptacles holding the open'ends of the same against said openings whereby said receptac es are caused to vibrate with the vibrating member.

2. A machine of the class'described comprising a rigid receptacle-supporting member, means for rotating the same, a vibrating member, connections between the rotary member and the vibrating member whereby said vibrating member is rotated with the rigid member and resilient mountings on the rotating member for holding receptacles against the vibrating member whereby said receptacles vibrate with the vibrating memher.

3. A machine of the clam described, comprising a table, a plurality of cups in said table, means for vibrating said table, a rotating table beneath the vibratin table, and connected thereto, a pluralit o receptacle supports on; said rotating ta le and means for causing said supports to hold receptacles beneath said cups and vibrate therewith.

4. A machine of the class described, comprisitig a table, means for rotating the same, a plurality of spring pressed supports on said table ada ted to hold receptacles, a table above sai rotatin table provided with a plurality of cups, sai supports and cups adapted to hold receptacles vbetween them and means for vibrating the upper table.

5. A machine of the class described, having a vibrated supporting member, a filling cup held therein, said cup having an up wardly widening conical openin a apted to receive filling material, and a ownwardly widening conical opening extendin from the filli opening, and a support eneath said cup avin'g a conical opening adapted bers and in position to receive as a seat for the lower end of a receptacle held between the support and cup and means for'causing the receptacle to vibrate with the cup.

6. In a machine of the class described, a pair of rotary, spaced-apart members, one of said members bei situated above the other, means for rotating one of said members, a connection between the rotated memher and the other member whereby both members are rotated together, a plurality of filling cups on one of said members, means for vibrating said cup-holding member, and a plurality of resilient receptacle-supports for holding receptacles between the mema filling preparation through the filling cups.

7. A machine of the class described, comprising a pair of rotary members connected together and adapted to rotate in unison, one of said members having a plurality of openings through which a filling preparation is passed, means for resiliently sup porting receptacles between the members with the mouths of said receptacles in position to receive filling pre aration through the openings and means or vibrating the perforated member.

8. A machine of the class described, comprising a pair of rotary members mounted one above the other, said members being connected together and adapted to rotate in unison, means for vibratin the upper member independently of the ower member and means on the lower member for supporting receptacles against the upper member so that said receptacles vibrate therewith.
